COMBINED THREAD GUARD AND SPINNING-RING HOLDER.

Application filed November 10, 1922.

certain improvements in means for protecting each ring and its traveller in a spinning frame from dirt, lint, moisture, etc., and at the same time serves to hold each ring in position on'the rail.

Certain features of the invention, as the means for protecting the ring and traveller, may be employed without the ring holding feature and thus the benefits of protection referred to may be obtained.

It is well understood by those skilled in the art that in ring spinning, lint, etc.-, accumulates upon the travellers to such an extent as to interfere seriously with the movement of the traveller, causing it to load up on the ring, and also cause breaking of the threads. Various devices have been used to prevent this accumulation, but so far as 1 am aware, none of them has been successful. Under the present invention, a very important feature resides in the provision of a protector for the ring which partially encases the latter, and has an overlapping or extended portion which guards the ring and traveller from the flying lint and small particles of thread. This protector is applied to each ring of a frame, and very effectively prevents the lint from one traveller from being thrown against an adjacent traveller, and in fact protects all of the rings and travellers in the spinning frame from lint. deposits.

Another important feature of the invention is comprised in a holding means for securing each ring upon the rail in such man ner that the ring is capable of easy removal.

Preferably the holding means is combined with the protector above described whereby a single element is utilized to perform the two-fold functions of protecting the rings and travellers, and of securing each ring to the rail.

The above, and other valuable features of the invention will. be more fully described hereinafter by reference to the accompany- Selial No. 600,116. 7

ing drawings, and the novel elements will be pointed out in the appended claims.

In the drawings:

Fig. 1 represents a plan View of a portion of'a spinning frame, comprising a rail section with three rings thereon, and the present improvements applied;

Fig. 2 is a front elevation of Fig. 1;

gig. 3 is a section on the line 83, Fig. 1 an Fig. 4 is a section on the line l, Fig. 1.

The rail 2 of a ring spinning frame is provided at suitably spaced intervals with the usual openings 3 to receive the bobbins.

Under the present invention, surrounding each opening 3 is a recess 5, of a size and shape to receive and snugly fit the base flange of a spinning ring 6. Such spinning ring, as shown herein, is of the double flange type, and the upper flange or raceway receives the usual traveller 7; The upper flange 8 of the spinning ring, and the lower flange 9 thereof are, in the type of spinning ring herein disclosed for purposes of illustration, arranged at right angles to the body portion of the ring which may be provided with a central head 10. The space between the flange 8 and the head 10 constitutes the raceway for the traveller 7.

The forward portion or edge of the rail 2- is reduced in thickness, as shown at 12, to provide a shelf 14. When the rings are placed in position on the rail the shelf 14 will extend immediately in front of the rings, and by reason of the fact that the material of the rail is reduced or cut away at this point the piecing up of the thread by the operatives is greatly facilitated, as access is readily afforded to the front of the ring and the fingers of the operator are permitted full freedom of movement. Sue

tained upon the rail is'a longitudinal strip 16 having one or more out out portions therein, according to the number of rings on the frame. Each out out portion of the ring and extends above the ring a distance sufiicient to provide the proper amount of clearance for the traveller so that the same may operate freely without obstruction by said flange, and it extends inwardly far enough to protect the ring and traveller from flying lint, dirt, moisture, etc. The protection afforded by the flange 18 to the ring and traveller is such as to prevent the accumulation of lint or other foreign matter on the traveller due to the flying lint in the mill, and additionally prevents the deposit of lint thrown off from one traveller from accumulating upon an adjacent traveller. Furthermore, the flange overlies the traveller and is in such proximity thereto as to hold it in true alignment with the ring so as to permit bowing of the yarn. The opening from the front of the enclosure afforded by the flange 18 also acts to clear the traveller and ring from such lint as may have been deposited upon these parts, and the same will be thrown out to wards the front edge of the rail as the traveller revolves.

The lower portion of the strip 6 at each recess or cut out part 20 is formed as an extension or flange 22 which overlaps the base flange 9 of the ring, as shown in Fig. 3. The strip 16 is held to the ring rail by any suitable means, and conveniently screws 2 1 are employed, the same passing through the strip and rail and thus clamping each ring firmly in the recess'5. In this construction, in order to remove any one of the rings from the frame it will simply be necessary to unscrew a suitable number of the screws 24 to permit the strips 16 to be lifted slightly, thus permitting the ring to be raised clear of the recess 5 and removed from the rail. 7

It will be understood that the protector comprising the flange 18, and the ring holding means comprising the flange 22, may be used for a single ring or for any number of rings in a spinning frame. In the'draw ings but three rings are illustrated in conjunction with a combined protector and ring holder having the required number of openings, and protecting ring holding flanges for the rings illustrated, but it is contemplated in practice to employ the device in connection with as many rings as will be sustained upon the spinning frame. It will also be understood that changes may be made in the details of construction, or the arrangement of the elements illustrated without departing from the spirit of the invention, providing such changes fall within the scope of the following claims.

Having thus described my invention,

what I claim as new and desire to secure by U. S. Letters Patent 1s:

. thread guard, comprising in combination with a s inning rin rail an overhanging protecting flange arranged above the spinning ring and extending partly but not wholly around the circumference of said ring.

2. In a thread protector for spinning rings, the combination with a ring rail, of a ring thereon and an enclosing means for the raceway arranged to extend above and to overlap a portion of the ring, said device also extending circumferentially around a substantial portion of the circumference of the ring, but not wholly around the ring.

3. In a thread protector for spinning rings, the combination with a ring rail, of a rin' thereon, and enclosing means arrange to extend around at least one-half of the circumference of the ring, and shaped to overlap the ring flange and traveller thereon.

4. In a thread protector for spinning rings, the combination with a ring, of a protector shaped to partly enclose the upper portion of the ring, and to extend circumferentially thereof a distance substantially one-half the circumference of the ring, leaving the remaining portion of the ring free from said enclosure.

5. In a device of the class described, the combination with a spinning frame and a plurality of spinning rings thereon, a plurality of enclosing devices on said frame each extending a substantial distance around a ring and overlapping the flange thereof, but leaving the front portion of each ring free from said enclosure.

6. In a device of the class described, the combination with a ring rail, of a ring thereon, and means for enclosing a substantial portion of the raceway on said ring, said means overlapping the ring at its circumference, but open at the front' portion of the frame, whereby to permit the lint to be thrown off from the traveller after passing beyond the limits of the protecting device, said means being further provided with a device for holding the ring upon the ring rail.

7. A combined protector and spinning ring holder, comprising, in combination, a
